Question
A man spends 12% of his salary on rent and out of
remaining he spent Rs.7x on households and he saved the remaining amount i.e. Rs.4x. If the difference between spending on rent and saving is Rs.1800, calculate his monthly salary.Solution
ATQ,
Let salary = S Rent = 12% of S = 0.12S Remaining = 0.88S Household = 7x, Saving = 4x So: 7x + 4x = 0.88S → 11x = 0.88S → x = 0.08S Saving = 4x = 4 × 0.08S = 0.32S Rent = 0.12S Difference = 0.32S - 0.12S = 0.20S = 1800 0.20S = 1800 → S = 1800 / 0.20 = 9000
